JOHN E. LIND, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR TO JOSEPH W. WOOLLEY, OF COLUMBUS, OHIO.

INTEBVIEWER.

Application filed June 9,

This invention relates to an interviewer which is capable of a wide range of use but is particularly adapted for use on the doors of apartments.

An object of my invention is to provide means upon the interviewer whereby a caller can attract the attention of the occupants of the apartment, which means is at the same time part of the interviewer itself. The means for attracting the attention of the occupants is disposed so as to add to the attractiveness of the interviewer and also to serve as a bar member upon the outside member of the interviewer thereby further preventing any possibility of access through the interviewer itself to the inside ofthe door.-

It is also my intention to provide means whereby the entire interviewer can be attached to a door which has only a single opening provided therein. This is important since my interviewer can be attached to the door inv a minimum of time and also by unskilled labor.

A still further object of the invention is to provide an interviewer which is capable of'being used upon the type of doors common- 1y known as servidors.

Vith these and other objects in view as will hereinafiter appear, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are ettained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my device attached to a door;

gigure 2 is a vertical cross sectional view, an

Figure 3 is a part elevational and part cross sectional view of a detail.

In the drawings like reference characters refer to like parts.

My deviceconsists essentially of two plate members 10 and 11. The plate member 10 is placed upon the outside of the door and the plate member 11 is placedupon the inside of the door. These plate members are preferably circular but may be of any desired shape. A portion of the door is indicated at 12 having a circular opening 13 therein. I Plate members 10 and 11 are provided with alined openings 14 and 15 respectively, the opening 14 being slightly less in diameter 1928. Serial No. 284,245.

closed in the application, Serial No. 2550,754 I filed-May 26, 1928 and need not further be described.

The outside plate member 10 has a bar 16 extending diametrically across the opening 14 therein and which has an enlarged central portion 17 having an aperture 18 therein in which is pivoted the shank 19 of the turnable key 20. The shank 19 has an enlarged boss 21 thereon which limits the movement of the key member inwardly while upon the other side of the bar 16 a washer 22 is disposed which is held in place by a key or pin 23 pass ing through a slot 24 in the shaft member 19.

The shaft member terminates in a reduced threaded lug 25 and this lug is adapted to be screwed into a connecting member 26 having the threaded socket 27 therein. The connecting member can be made of various sizes so as to accommodate different thicknesses of doors and upon the end opposite to the threaded socket 27 a tapered squared recess 28 is provided. v

Carried by the door member 29 is a mechanical bell 30 having the usual step-up gears 31 and the usualknockers 32 which are adapted to ring the bell 33. The main shaft for operating the bell 30 is indicated at 34 and this tween the key member 20 and the bell operating mechanism so that when the bell is run g a person upon the inside of the door can release the latch 37 and pivot the door member 29 upon the hinge 36 away from the aliued openings 14 and 15 and inspect the person ringing the bell before opening the door. A thinconnecting member 64 is placed between the front plate 10 and the door member 29.

The operation of the device is believed to be clear. Upon lifting the door member 29 away from the openings 14 and lathe con nection is broken at 28 and 35 between the key' member and the bell mechanism.

Upon closing the closure member 29 the tapered coacting portions 35 and 28 will allow the key member 20 to adjust itself and the tapered portion 35 will seat itself fully in the tapered recess 28 leaving the parts in operative position for the next caller.

The connecting element 26 is of importance since the thicknesses of doors vary considerably and it is merely necessary to change the length of this connecting portion 26 to take care of all the various thicknesses without changing any of the remainder of the structure.

It is of course to be distinctly understood that the separable connection shown at 35 and 28 is merely illustrative and that any other separable connection may be used. The desic eratum to be obtained is a means for breaking the connection between the key 20 and the bell mechanism so as to allow the closure member 29 to be opened. It will be noted that the device provides an interviewer and at the same time a bell mechanism for sum moning the occupants of the apartment. It is also understood that the particular bell mechanism shown is merely illustrative since there are a plurality of constructions which will be highly suitable in a construction of this type.

Some changes may be made in the construction and arran ement of the invention set forth above, without departing from the real purpose and spirit thereof, and it is the intention to cover by the following claims, any modified form of structure or use of equivalents, which may be reasonably included within their scope.

I claim:

1. An interviewer for a door or the like comprising means for securing'the interviewer to the door, a bell pivotally mounted upon said interviewer so as to move from and toward said door and means for operating said bell.

2. An interviewer for a door or the like comprising a closure member and an outside member, a bell mounted upon the closure member of the interviewer and movable therewith so as to move from and toward the door,

mechanism mounted upon the outside plate member of the interviewer.

1-. An interviewer for a door or the like comprising an outside member, an inside member spaced from said outside member, bell mechanism mounted upon said inside member, operating means for said bell mechanism mounted on said outside member and a separable connection between said operating means and said bell mechanism.

5. An interviewer for a door or thelike comprising means attached to the door permitting a sight opening therethrough which is normally closed by a closure member, bell mechanism mounted upon said closure member and a separable operating means for said bell mechanism.

6. An interviewer for a door or the like comprising a pivoted closure member, signalling means mounted upon said closure memher and a separable operating means for said signalling means.

7. An interviewer comprising plate members secured to a door, a closure member pivoted upon one of said members, signalling means mounted upon said closure member and movable therewith so as to move from and toward the door, and operating means for said signalling means mounted upon the other plate member.

8. An interviewer comprising inside and outside plate members having alined apertures therein, a closure member pivoted to the inside plate member for closing said alined apertures, signalling means mounted upon said closure member, a rotatable key mounted upon said outside plate member and a separable connection between said key and said signailing means.

9. An interviewer comprising an outside member, an inside member spaced from said outside member, said members having alined openings, a closure member mounted upon Y said inside member forclosing said openings, a bell mechanism mounted upon said closure member, an operating shaft for said bell mechanism having a tapered squared end,

operating means for said'bell mechanism piv otally mounted upon the outside member, a connectlng member secured EQSRlCl operating means havmg a squared recess therein for cooperating with the squared tapered end of the operating shaft of said bell mechanism.

10. An interviewer comprisingplate members secured to a door, each of said pla'temembers being provided with a single aperture and said apertures being alined and constituting a sight opening, a closure member pivot i ed upon one of said members, signalling means'disposed upon one of said members and means for operating said signalling means extending through said alined apertures.

11. An interviewer comprising plate members having alined apertures secured to a door, a pivoted closure member upon one of said plate members swinging from, and toward the door, signalling means upon said closure member and means for operating said Signalling means only when said closure memher is disposed substantially parallel to said door. 7
